BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phlox plant, botanically known as Phlox paniculata and hereinafter referred to by the name ‘Appofalp’.

The new Phlox plant is a product of a planned breeding program conducted by the Inventor in Andijk and Hazerswoude-Dorp, The Netherlands. The objective of the breeding program was to create new compact and vigorous Phlox plants with numerous large flowers.

The new Phlox plant originated from a cross-pollination in August, 2009 in Andijk, The Netherlands, of a proprietary selection of Phlox paniculata identified as code number 047-08-010, not patented, as the female, or seed, parent, with a proprietary selection of Phlox paniculata identified as code number 047-08-008, not patented, as the male, or pollen, parent. The new Phlox plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Hazerswoude-Dorp, The Netherlands in August, 2010.

Asexual reproduction of the new Phlox plant by terminal cuttings in a controlled greenhouse environment in Andijk, The Netherlands since 2014 has shown that the unique features of this new Phlox plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Phlox have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Appofalp’. These characteristics in combination distinguish ‘Appofalp’ as a new and distinct Phlox plant:

1. Upright and relatively compact plant habit.

2. Freely flowering habit, numerous large soft purple-colored flowers with light purple-colored centers.

3. Long flowering period.

4. Good garden performance.

Plants of the new Phlox and the female parent selection differ primarily in the following characteristics:

1. Plants of the new Phlox are more vigorous than plants of the female parent selection.

2. Plants of the new Phlox and the female parent selection differ in flower color as plants of the female parent selection have red-colored flowers.

Plants of the new Phlox and the male parent selection differ primarily in the following characteristics:

1. Plants of the new Phlox are more vigorous than plants of the male parent selection.

2. Plants of the new Phlox and the male parent selection differ in flower color as plants of the male parent selection have dark purple-colored flowers.

Plants of the new Phlox can be compared to plants of Phlox paniculata ‘Appofamcer’, disclosed in a U.S. Plant patent application filed concurrently. Plants of the new Phlox differ primarily from plants of ‘Appofamcer’ in flower color as plants of ‘Appofamcer’ have red purple-colored flowers.

Plants of the new Phlox can also be compared to plants of Phlox paniculata ‘Anastasia’, not patented. In side-by-side comparisons, plants of the new Phlox and ‘Anastasia’ differ in the following characteristics:

1. Plants of the new Phlox are more compact than plants of ‘Anastasia’.

2. Plants of the new Phlox and ‘Anastasia’ differ in inflorescence shape as plants of ‘Anastasia’ have cone-shaped inflorescences.

3. Plants of the new Phlox and ‘Anastasia’ differ in flower color as plants of ‘Anastasia’ have pink-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Phlox plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Phlox plant.

The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Appofalp’ grown in a container.

The photographs on the second sheet are close-up views of typical inflorescences (upper photograph) and typical leaves (lower photograph) of ‘Appofalp’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer in 15-cm containers in an outdoor nursery in Mijdrecht, The Netherlands and under cultural practices typically used in commercial Phlox production. During the production of the plants, day temperatures ranged from 10° C. to 25° C. and night temperatures ranged from 4° C. to 15° C. Plants were pinched five weeks after planting and were 19 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
